Done, right? Then assign drives, right?

Okay. Array has been Reset(please configure)

I am such a novice.. okay I am still at this step . I will apply and proceeding with steps.

Oh okay.

I may lose data that on disk 7, right? In the original configuration I had a disk7 in the array.

I could use this drive to rebuild disk 2.

Should I use the spare unassigned precleared 16TB drive?

Okay thanks.

Okay. correct selection?e t

Thanks. I appreciate your help . I have a 16TB (never used in Unraid) drive that been precleared a few months ago. I am thing about rebuilding disk 2 with this drive. Okay with end inside of tools now. Preserve current assignment is gray out now. How to I select the option retain all?

I started before I received your instructions. I wish I had waited for your instructions. But I didn’t know I was going to get help at that time and made some not so great decisions. Any suggestions what I can do now?

Well I took some different action on unraid before I had your insight on what steps to take. Yes. Disk 2 is failing while I was forced to rebuild disk 7, because disk 7 I’d was scrambled. Now estimated completion time is a crazy number like 2000 days plus keeps on going up and down at one time it was at 300 days.. I guess overall unraid server’s failure is eminent for me. Wish I knew what to do to make it better. It’s been quite a journey so far four years in and now it looks like the whole system is gonna fail on me.

The diagnostic file. thecave-diagnostics-20260115-2107.zip

I began the process. I have my fingers crossed. Before I started I physically looked at all drives and compare the serial numbers. Disk 7 like I stated before the serial numbers is off my a few characters (wondering what happen? Maybe I will find out later) So Disk 7 is rebuilding now and the finish time is not normal. I hope this will change with time. ( I feel like there is some serious issues happening) Take a look: The diagnostic has been running for a while. Maybe I should have ran before starting the current process of rebuilding. Never had anything like this happen before in 3.5 years running my Unraid server. I hope the server will survive. (Note the days count is constantly changing)

Anyone have similar experience and if so what did you do?

Just looking at disk history.

The options I have:

Update: I was able to reassign some drive back to the original slot. Except one drive is off by one character. Also warning that disk 2 is failing. See below. Moreover, should try to see if i can make Disk 7 match or just try to start the array?

What happen is the original Disk 2 was giving me intermittent read errors. These errors warring would disappear and reappear in a few days. So I decided to swap out the drive. When I brought the system back up, I was having this issue of not all drives in array. (missing drives. etc.) So multiple times I moved the drives sata power cable around to try to balance the power. This usually would work. But after a few days I was this maybe it is something else. I got a new 1000 watt power supply and similar hba drive controller. I swapped out the power supply first and started server, no change. Then swapped out the old hba with new hba and sata cables. Now I see all of the drives under the unassigned listing. I tried to assign the drives back to there original destination. I get wrong drive status. There are a few steps I am thinking about trying: Place Disk 2 back in server. (original drive still works. just give me the intermittent errors) Place the original hba controller card back in server. ( It seems not to see the drives. Maybe it is fine?) Hopefully, I can solve this issue.

Still having issues with unraid. Tried to resign drives to corresponding disk number. Wrong drive is indicated even though it matches drive the information that is displayed.

In the past I would have and issue with all drives starting in array after shutting down. I would move the power connects around to drives and reboot again. Would work most of the time. Having a 850 watt power supply I was thinking server was having issues with 8- HDD and 4 SSD drives or the HBA/ sata cables were failing. I replaced the PS with 1000 watts and a new HBA card. Now it is seeing more drives, but most are unassigned and has a active mount button. The parity drive does not have a mount button option. Tried to see if I could assign the parity drive back to it's configuration and unraid stated it was the wrong drive. Is there any way to fix this issue? Any help will be appreciated. thecave-diagnostics-20260114-1754.zip

Anyone experienced this issue?

I understand. There is a logic to the way cache drives are utilized. Okay if I was starting over with unraid as a beginner what guides or video would be good to develop a cache foundation to build on. (I feel maybe I added configuration steps from many sources) Looking at my drive/cache configuration how does it look ? Okay or something I need to look at? Anything thing pop out as maybe a bottleneck? Any suggestions would be greatly appreciated.
